The K7RA Solar Update  Kijk naar?

Last week's Propagation Forecast Bulletin ARLP002 opened with "Wow!"
I don't know what to say about this week, except it is beyond wow.

This actually has me thinking about Solar Cycle 19.

Lately we have seen solar flux at the same levels we saw at the peak
of Solar Cycle 23. If we are about 30 months away from the peak of
this Solar Cycle 25, could this get us to the 1957-59 levels last
seen in Solar...

The K7RA Solar Update  Kijk naar?

Wow! Sunspot numbers up, geomagnetic disturbances down. What could
be better? Okay, maybe Solar Cycle 19, but that was 66 years ago and
by far the all time largest.

But this is now, we are in Solar Cycle 25, and this sunspot cycle is
emerging better than the consensus forecast. It is predicted to peak
about 30 months from now in Summer 2025.

Solar cycles tend to ramp up faster than they decline, so w...
